Apparatuses for delivering a predetermined quantity of content from a pressurized container are provided. The apparatuses include (a) a container (12) capable of housing a pressurized gas and a content, the container including a valve in fluid communication with the content; (b) a release assembly (8) for releasing content from the container, where the release assembly is in fluid communication with the valve; and (c) a rotatable assembly (1), where the rotatable assembly includes a wheeled actuator (2) having a plurality of sides (4) and angles (5). The wheeled actuator of the apparatus is positioned for engagement with the release assembly. Engagement of the wheeled actuator with the release assembly moves the release assembly from a first closed position to a second open position. In some embodiments, the apparatus includes one or more wheeled switches. Methods for delivering and applying a predetermined quantity of content from a pressurized container are also provided. |
